Abstract: The author proposes consideration of d-c electrification and third-rail distribution for extensions of British Railway's Southern Region electrified operation. With this he would expand the working of multiple-unit trainsets and introduce a tractor unit, a compromise between locomotive-hauled and true multiple-unit trains. He notes that ac electrification is favored if all trains are locomotive-hauled since substations are carried on the locomotives and can be utilized fully. For various reasons locomotive-hauled stock is not suitable for suburban service. He proposes an improved 1500-volt dc conductor rail mounted between the running rails and suggests solutions for problems occasioned by switchwork.
